Horns are removed because they can pose a risk to humans, other animals and to the bearers of the horns themselves (horns are sometimes caught in fences or prevent feeding). Dehorning is only recommended with local anesthesia and sedation by a veterinarian or a trained professional, [ 4 ] although a 2011 study showed that only 10% of dairy ...
Planorbarius corneus, common name the great ramshorn, is a relatively large species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails, or planorbids, which all have sinistral or left-coiling shells.
A pair of horns on a male impala Anatomy of an animal's horn. A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct from antlers, which are not permanent.
Two-horned rams typically have horizontal double-curled horns. Four-horned rams have two vertical centre horns which may be 61 cm (2 ft) or more in length, and two smaller side horns, which grow down along the sides of the head. The horns on the ewe are smaller in diameter, shorter in length and appear more delicate than those of the ram. [26]
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs.Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. [3]
In 1825 Alexander Riley was the first Australian breeder to obtain a poll ram with a view to establishing a poll Merino flock. The ram was imported by him from Germany, along with Saxon ewes. Boonoke, Bungaree, Uardry and Wanganella studs made specific mention of "poley" or poll rams for sale from the early 1880s.
Cut in cross section, the hippocampus is a C-shaped structure that resembles a ram's horns. The name cornu ammonis refers to the Egyptian deity Amun, who has the head of a ram. The horned appearance of the hippocampus is caused by cell density differentials and varying degrees of neuronal fibers.
Similar to species with horns or antlers, male giraffes use their ossicones as weapons during combat, where they use their heads as clubs: the ossicones add weight and concentrate the force of impact onto a small area, allowing it to deliver heavier blows with higher contact pressure. [4]
